A “multi-site” church is a church that has attempted to deal with church growth and outreach in a different way. 

Two traditional ways of addressing church growth are:
•  Building a bigger building (Single organization in a single location)
•  Creating daughter churches (multiple organizations at multiple locations)
 

But there are at least two other variations possible:
•  Multiple organizations at a single location (“time-share” church)
•  Single organization at multiple locations (multi-site church)
